      The TimedElement that controls the timing of this animation.
    • animatableElement

      protected AnimatableElement animatableElement
      The AnimatableElement that gives access to underlying values in the document.
    • lowerAnimation

      protected AbstractAnimation lowerAnimation
      The animation that is lower in the sandwich.
    • higherAnimation

      protected AbstractAnimation higherAnimation
      The animation that is higher in the sandwich.
    • isDirty

      protected boolean isDirty
      Whether this animation needs recomputing.
    • isActive

      protected boolean isActive
      Whether this animation is active.

      protected AnimatableValue composedValue
      The value of this animation composed with any others.
    • usesUnderlyingValue

      protected boolean usesUnderlyingValue
      Whether this animation depends on the underlying value.
    • toAnimation

      protected boolean toAnimation
      Whether this animation is a 'to-animation'.
  • Constructor Details

  • Method Details

    • getTimedElement

      public TimedElement getTimedElement()
      Returns the TimedElement for this animation.
    • getValue

      public AnimatableValue getValue()
      Returns the value of this animation, or null if it isn't active.
    • getComposedValue

      public AnimatableValue getComposedValue()
      Returns the composed value of this animation, or null if it isn't active.
    • toString

      public String toString()
      Returns a string representation of this animation.
      Overrides:
      toString in class Object
    • usesUnderlyingValue

      public boolean usesUnderlyingValue()
      Returns whether this animation depends on the underlying value.
    • willReplace

      protected boolean willReplace()
      Returns whether this animation will replace values on animations lower in the sandwich.
    • markDirty

      protected void markDirty()
      Marks this animation and any animation that depends on it as dirty.
    • sampledLastValue

      protected void sampledLastValue(int repeatIteration)
      Called when the element is sampled for its "last" value.
    • sampledAt

      protected abstract void sampledAt(float simpleTime, float simpleDur, int repeatIteration)
      Called when the element is sampled at the given time. This updates the value of the animation if active.
